After last week’s gorgeous “Dazed,” 15 year-old Ukrainian Tülpa returns alongside Belgian co-producer BA฿EL as duo O L V (pronounced “olive”) with another beautiful, ambient song, “Close to Us.” Airy and entrancing (thanks in large part to the ethereal, disjoint vocals of collaborator Låpsley), “Close to Us” is perfect music for getting lost in your thoughts, shutting off the outside world and escaping to parts unknown. A fine introduction to a promising duo.
